<p>I got 10cos75</p>

<p>The one with the 2 squares and it said that one side was increased by L, so what would the diagonal be increased by… what was the answer?</p>

<p>also 1 - pi for a shaded region question?</p>

<p>The one with the 2 squares and it said that one side was increased by L, so what would the diagonal be increased by… what was the answer?</p>

<p>wondering the same thing!</p>

<p>@NYJ3TSFAN It was 4 - pi I think
The radius was 1, which makes the sides of the square all 2
So A of the square=4 and A of the circle=pi
4 - pi
And it was sqrt(2), lovelytexan</p>

<p>SQroot of 2 x L was the answer to the increase in the diagnol.</p>

<p>oh yep its 4 - pi. wasnt thinking and made the stupid mistake of making the radius the sides of the square dang
thanks</p>

<p>What was the answer to the parrologram question where u had to use the height of the parrelogram and trig to find the base of the triangle at the end of the parrelogram. Was it like x = (whatever the length was)/ tan (whatever the angel was) ?</p>

<p>i think i put 20/ tan50 ? or maybe it was 30/tan50</p>

<p>I think I remember it being tan50/20?</p>

<p>The 1 foot blue flag question was 15 total right?</p>

<p>I got for for the blue flag questioin</p>

<p>3 med and 5 large
it was 5 meter or feet for each
3x5 = 15
5x5= 25
15+25= 40</p>

<p>@lovely</p>

<p>Was it really 5 for each?</p>

<p>I thought it was like three for each (maybe i dont remember correctly)</p>

<p>I also remember it definitely NOT being 5 each…</p>

<p>@Aqua</p>

<p>Do you remember it being 3 each?</p>

<p>it was 3 each. i think i got a total of 24?!</p>

<p>@NY</p>

<p>Yes that is what I got.</p>

<p>Phew!</p>

<p>I got a total of 24</p>

<p>It was 3 for medium flags and 5 for large flags. for sure. but i thought he had 3 med and 3 large flags, not 3 and 5.</p>

<p>what the function one? What was the value of b.</p>

<p>For the question about the degrees of the central angle, does anyone remember all of the answer choices? I can’t remember which one I picked without seeing all of them.</p>
